DIY - B6 1.8t - Vacuum line and Check Valve removal/simplification

[B6Lovin]

ok, thats all well and good IF you have the software, but what about emissions? what is the most of this vacuum line junk that can be removed without failing (passive or aggressive) emissions testing?

that all depends.

i don't have ANY of it. but i can pass emissions no problem.
this is going off the fact that I have people in my area who either A)don't care to poke around under the hood or B)wouldn't know what the hell they were looking for even if they did.

also my tune sets all my readiniess codes to pass permanently, so when they plug me into the machine i pass no problem. as long as they can beep my horn and flash my lights it's all gravy

well considering i live "in your area", you could PM me the locations of said people...

All you need is the block off plate.

Look at the pic I drew up (which took me forever by the way, lol) that is the way your vacuum lines should look if you have the stock N75 and TIP

so as of right now u have no Cel's right?

[dougyfresh]

i said three best.

as in easiest/most cost effective/you're getting a better tune for a BT/BAT setup anyways

Opps. I didn't read the word 'best'. Sorry.

[A4ringedONE8T]

I just mean that your stock tb and im are restrictive. You should pick up one with the r32 tb from Issam

I already have an R32 TB as well as an adaptor plate for the OEM or big port mani, but one of these days Im going to make a new mani and plenum for the larger TB ... in my spare time I dont have

[A4ringedONE8T]

why doesnt shawn have an evap setup?

Cause I took it out!

[absolutegtr]

Oh I have CEL's...I just dont understand how one light can bug so many people, unless its because you cant pass emissions .....

Boy am I glad there are ZERO inspection in SC

[dougyfresh]

Because when its lit up for something stupid as SAI it conceals being lit up for something more important (misfires, bad O2, etc..) which could, potentially, lead to big problems.

I guess thats true...but I make it a habit to check my CEL every week whether or not there is something wrong with my car. But I see where your coming from.....

misfires = flashing CEL, as long as you vag the car regularly and know your car, nothing to worry about

[absolutegtr]

misfires = flashing CEL, as long as you vag the car regularly and know your car, nothing to worry about

To add to that, if your CEL is already on (say for SAI pump) and you start misfiring, the CEL will still flash.

Happened to me about 2 days ago (that whole vacuum leak problem)

[dougyfresh]

Nope.

I get misfires and my CEL does not flash. They are 'soft' misfires. Intermediate misfires.

The CEL flashes if you are misfiring 100% of the time.

Must be because of that tiny turbo

[dougyfresh]

Must be because of that tiny turbo

Nope. Its because my cold-start idle isn't finalized. Only happens on cold starts. But that is getting fixed as I type this

[sloweryucf]

Are there ways to remove things in stages? Like if someone doesn't want to remove everything but just some things?

I removed all my smog crap on my motorcycle and that was cake, but a car is a little bit more involved and it's my daily driver.

Of course, SAI, EVAP, Crank/VC vent, N249, and the suction pump are all different systems that do different things

You sure it's not the cold plugs you are using?

[dougyfresh]

You sure it's not the cold plugs you are using?

Positive.

I got rid of those cold copper plugs and put new F5DPORs in. I also advanced the cam gear a tad (to where BobQ wanted it) when I swapped plugs. Same problem at start-up but its not as pronounced. My cold start was always a slight problem. Even on the stock 1.8T with GT28RS. Its in the software. We never 'finished' that part of the software.

[CO AVANT]

Both those types of plugs gave/give me the same symptoms. Have you tried a stock heat range or 1 range colder to see if there is any difference?

Nope. Guess I could have put my NGK copper plugs (B6 something or other) in but I never thought about that. I ran those plugs when I was k03.

that's the spirit! you steal one of adrian's spares? hahaha

if you end up ganking one from issam instead of making your own (or if you end up with a similar design) PM me and I'll try to remember the list of things that didn't fit/had to be modified on my car to make it fit.

mark give you an ETA for getting the tuning done?

I'll make my own when I get time, dont like Issam's, shits ugly

ugly my ass. that thing is gorgeous.

better than that scrawny POS tucked up in your engine bay

[A4ringedONE8T]

Only IM that would ever make it into my engine bay other than my own would be an SEM ... there stuff is the SHIT, and purdy too!

how are you gonna bolt a year old solidworks drawing to your engine

i keed, they make awesome stuff... they just procrastinate as much as just about everyone else when it comes to getting out products for the longitudinal motors.

[A4ringedONE8T]

Not a big market for it, how many people have bought Issam's mani? 1? lol kidding

For the cost anways, even the SEM, I would make my own

[k0mpresd]

True. but you know that they (most A4 owners) can't do that.

thats not my problem. haha.

[AudiA4_20T]

I just pulled off the fender liner and ripped the rest of the sai shit out

[AudiA4_20T]

wait, no I didnt, that piece in the front also connects to the rear fender liner WTF,

then I tried to disconnect that but theres ANOTHER LINE WTF

[AudiA4_20T]

sorry to be annoying but that thing in the back is actually the "leak detection pump" (#11)

[B6Lovin]

the lines that go down the drivers side and to the spare tire well are for evap/the charcoal canister.

[absolutegtr]

Furthermore, if you take out the drivers side fender, the vacuum resevoir is located their which you can also take out....or is that what you were talking about?

[02A4_B6]

i just got done changing my "rear coolant flange" and what a pain due to having to remove most of the hard piping shown in this DIY. Just wondering, i have vag-com, basically completely stock motor except for porsche diverter valve. can i use the vag-com to set the readiness so i do not get a "CEL" from having the SAI system removed?

[02A4_B6]

Almost 24 hours and no input from anyone?

No it is not something you can do with vag-com as has been said a few times in the thread already. It is only something the tuners can do as they write the software

Hopefully my block off plate will be here in a couple of days. Shawn you wanna do another write up with your DSLR ?

Aww come on now, the pics seriously arent that bad.

it's just a ploy to get some help

[absolutegtr]

It really is very easy.

In all honesty, I really didnt know 100% what I was doing when I started but, as I went along it all started to make sense, on what each system does and what to take off and what to leave.

Those two links are crucial for you to read and then it all comes together!
